[PHP] Automatically update other sections of page
Hi, I've created a very advanced web form which acts as an application and I am in desperate need of help. The application works great, and it utilizes components such as combo boxes, checkboxes and radio buttons. It is split into sections using iframes, meaning that each section is scrollable to display the full repitoire of available information. The problem I have is every time a piece of information is updated, whether it is a selection or an alteration, my application needs to reset a number of times to reflect the change from the top down. The refresh allows my application to show the most current scenario, but the problem is there is a cascading effect and one click can result in three or four refreshes so that all the iframes are up to date. What I'm wanting to know is whether there is a way that this information could be updated without the need of the refresh? I'd need to update information above where the change took place, and some of the changes are simply text (ie an integer calculation could be different depending on which radio button is selected). Is this possible? I want to be able to click on a checkbox and the information related to that record is displayed below automatically without reloading or refreshing. Please help! Thanks, Michael.
[PHP] Variable passing through a form
Hi, I currently have a page divided into three areas, two of which are iframes. The user selects a component out of part 1, which decides what is shown in part 2. When something is clicked in part 2 the information updates in the second iframe, or part 3. This is all working fine through $PHP_SELF and target. I am now working in part 3 of my page which has already had variables passed to it from part 2, however when I try to make selections on this page which should update in the same area ($PHP_SELF) I am losing all the variables which were earlier passed. I have tried $REQUEST_URI also which didn't help. example: after coming from part 2 $REQUEST_URI might be test.php?var1=a&var5=f&var16=d . If I then select and option on this new form and then send it to itself I lose everything that was originally there (output might then be test.php?newvar=new) The line which executes my form is (currently) , and as I said $REQUEST_IRI does contain the variables on initial loading. I need to keep these initial variables and add the new (ie test.php?var1=a&var5=f&var16=d&newvar=new) Please help!

[PHP] Add On: Variable passing through a form
Sorry, but I forgot to say the variables froming from part 2 to part 3 can be anything between 1 and 30 or any combination thereof. will be no good here as it is too hard to pre-distringuish which variable names will be transferred Thanks Michael Benbow wrote: Hi, I currently have a page divided into three areas, two of which are iframes.

[PHP] Find all combinations of numbers
Hi,
I searched through the archives and found the following snippit of code
from Tim Converse from late 2000. This is great, but does anyone know
how I can adapt this so I can return all values from a multidimensional
array? I have an id number which corresponds to a record which I need
to revisit once I get all possible combinations (not just the max which
below gives us) and I do not want to lose the link between the id and
the number. For instance:
$number[0]['id']=5;
$number[0]['number']=500;
$number[1]['id']=7;
$number[1]['number']=500;
$number[2]['id']=23;
$number[2]['number']=750;
$number[3]['id']=3;
$number[3]['number']=1500;
$max is assigned the value 1350 in this example, so we know id 3 will be
eliminated off the bat.
What I need to get back are the combinations of ID's where their
corresponding number are less than or equal to value $max. So in this
instance I might get something like;
5
7
23
5&7
5&23
7&23
I have spent about 40 hours in the last three days on this problem alone
and I can honestly say I am stuck. You guys are my last hope. Please
help a desperate man!
Thanks,
Michael.

Tim's code:
function maximum_subset_sum ($max, $candidate_array) {
$working_array = array();
while ($next = each($candidate_array)) {
$candidate = $next['value'];
$sums_to_date = array_keys($working_array);
while ($marked_sum = each($sums_to_date)) {
$known_sum = $marked_sum['value'];
$possibly_new = $known_sum + $candidate;
if(($possibly_new <= $max) &&
!IsSet($working_array[$possibly_new])){
$working_array[$possibly_new] = $candidate;
}
}
if(($candidate <= $max) &&
!IsSet($working_array[$candidate])){
$working_array[$candidate] = $candidate;
}
}
$max_sum = max(array_keys($working_array));
$return_array = array($working_array[$max_sum]);
while ($max_sum != $working_array[$max_sum]) {
$max_sum = $max_sum - $working_array[$max_sum];
array_push($return_array, $working_array[$max_sum]);
}
return($return_array);
}
// example use
$best_sum = maximum_subset_sum(40, array(39,23,19,14,9,5,3,2,1));
print("Largest sum is " . array_pop($best_sum));
while ($value = array_pop($best_sum)) {
print(" + $value");
} // will print "Best sum is 23 + 14 + 3"

[PHP] Retrieving text file
Hi All,
I am completely new to all this, so please bare with me. I have
permission to use another person's text file which resides on his
server. Currently I manually download the file, process it in Excel,
then upload it into my MySQL database. I want to try to automate this
process, and the first step I see if getting the file from his server
onto mine for processing. I will be using a cron job for this.
This is what I currently have, but I get errors...
$WebFile="http://www.somesite.com/somefile.txt";;
$LocalFile="/path/to/somefile.txt";
$handle = fopen ($WebFile, "r");
$outhandle=fopen ($LocalFile,"w");
while (!feof($handle)) {
$buffer=fread($handle,4096);
fputs($outhandle,$buffer);
}
fclose($handle);
fclose($outhandle);
When I try running this I get error after error:
Warning: fopen("http://www.somesite.com/somefile.txt","r";) - No error in
trial.php on line 5
Warning: Supplied argument is not a valid File-Handle resource in
trial.php on line 7
Warning: Supplied argument is not a valid File-Handle resource in
trial.php on line 8
The last two lines repeat themselves until the script times out.
Help! I am desperate!! The file definently exists but I am stuck.
Thank you,
Michael.

[PHP] Fw: Processing checkboxes in Dynamic tables
My apologies, I was playing with the code and changed something before sending... Where it reads \n"; echo ""; echo ""; echo $trade; echo "\n"; . $trade=$trade+1; . } while. etc. Could someone please help me so only the variables which are checked before the submit button is pressed are parsed, eg p102, p107, p117, rather than every input variable which is initialised on the site? Thank you heaps in advace, Michael.
[PHP] Combo problems.. Multi Array??
Hi, I've got a problem which has left me scratching my head for the better part of a week. What I need to do is take x amount of items on one side, and somehow find all the combinations of y that fit in x. Now I know this doesn't make much sense but it is very hard to explain, so I'm probably better off giving an example. In this example just say I have three isntances of x; A, B and C. x can grow to as much as 5 or 6 (D, E, F). On the flipside I have two instances of y; [1] and [2] I need to find how many combinations there are where y can fit in x. The outcome, if working properly, should be... A [1][2] BC AB [1][2] C ABC [1][2] A [1]B [2]C AB [1]C [2] A [1]BC [2] A [2]B [1]C A [2]CC [1] AB [2]C [1] Does anyone have any ideas on how I could do this? As I said I'm completely stumped.

Re: [PHP] Combo problems.. Multi Array??
Thanks Mike, I have read up a lot on permutation but I'm not completely sure that this will solve my problem. From what I can gather permutation takes a sample (i.e. ABC) and tells you how many different ways it can arrange the letters, with order mattering. What I need to do is take a variable number of groups (in my example, 3) and then display the combinations of ways that my sample (in my example, 2) can be spread across the groups. I had a go at permutation based on your advice and while I was able to successfully find all the different combinations of ABC it did not help me in my need of dispersing the sample amongst the available groups. After I have my combinations I then need to process the data. The example again is as follows.. A [1][2] BC AB [1][2] C ABC [1][2] A [1]B [2]C AB [1]C [2] A [1]BC [2] A [2]B [1]C A [2]CC [1] AB [2]C [1] Think of the letters as being static amongst all possible combinations, and the numbers as the piece of data which is varying. In my actual code both fields are integers but this isn't really important here. Does anyone have any idea how I can do the above? Thanks so much, Michael.

This is called a permutation. Googling for "permutation formula" brings up any number of good links; the most succinct is probably http://www.mathwords.com/p/permutation_formula.htm, but most of the other top 10 links will give you the same answer with a bit (or a lot!) more explanation.
